Many European cities and regions struggle to make evidence-based decisions about public transport, rural mobility and emissions reduction due to fragmented data and the absence of shared digital planning tools. In Saxony-Anhalt (Germany), regional authorities, municipalities and transport operators lack a common platform for modelling and evaluating mobility scenarios consistently and transparently.
The project addresses this challenge by deploying Replan.city, a cloud- and agent-based modelling platform, for public authorities in Saxony-Anhalt. It is led by Replan GmbH (Berlin) and implemented in close collaboration with the Intelligent Mobility Network Initiative Saxony-Anhalt (NIIMO), a regional innovation project connecting the state transport authority NASA GmbH, ministries, municipalities and research institutions.
The proposal directly addresses NIIMO’s need for a shared digital environment that unifies fragmented datasets and enables consistent modelling across institutions. NIIMO, public transport operators and demand-responsive transport (DRT) operators currently lack tools for rapid scenario testing, integrated evaluation of public transport redesign, rural DRT deployment, accessibility and climate impacts. The customised Replan.city digital twin seeks to fill this gap by providing a collaborative, data-driven simulation framework tailored to regional planning workflows.
The project creates digital twins of Magdeburg and at least one additional city, enabling planners to test scenarios including public transport route redesign, DRT for rural areas, electrification strategies and CO₂ reduction measures. Approximately 20 professional users from municipalities and transport authorities will participate in workshops and live demonstration sessions. The platform will generate quantitative indicators for accessibility, ridership, travel time, costs and emissions for each scenario, thereby supporting evidence-based decision-making across Saxony-Anhalt.

Mobility data in Saxony-Anhalt is fragmented across institutions, and authorities lack shared digital tools to plan greener, more efficient and more inclusive mobility.
Replan.city creates a shared digital simulation environment that unifies fragmented datasets, enabling municipalities and transport authorities to collaboratively model and optimise public transport and mobility policies.
Replan.city is expected to reduce transport scenario planning and evaluation from months to days, enabling faster, evidence-based mobility decisions across Saxony-Anhalt.
